Hi, Mike. I haven't tried that combination, but it sounds good to me. All those great Italian flavors go well together. In the summer, I often serve crostini topped with pesto and chopped fresh tomatoes with Italian food. Also, people usually top osso buco with gremolata - a mixture of fresh minced garlic, lemon juice and parsley - to add some freshness to a braised dish. You could use some of your pesto for that, too.
Anyplace where people argue about food is a good place.
